Module Netplex_kit

module Netplex_kit: sig .. end

Netplex toolkit

class type virtual v_processor = object .. end

Same as processor, but the methods process and supported_ptypes are flagged as virtual

class empty_processor_hooks : unit -> Netplex_types.processor_hooks

This is an empty set of processor hooks, i.e.

class processor_hooks_delegation : Netplex_types.processor_hooks -> Netplex_types.processor_hooks

Takes a hooks object, and makes a class of it.

class virtual processor_base : Netplex_types.processor_hooks -> v_processor

A virtual (incomplete) base class for processors.

class protocol_switch_processor : (string * Netplex_types.processor) list -> Netplex_types.processor

The arg is a list of pairs (proto_name, proto_proc).

class protocol_switch_factory : string -> (string * Netplex_types.processor_factory) list -> Netplex_types.processor_factory

protocol_switch_factory name merge_list: Merges the factories in merge_list to a single factory.

val add_helper_service : Netplex_types.controller -> string -> Netplex_types.processor_hooks -> unit

add_helper_service ctrl name hooks: Adds a helper service name to the controller ctrl. The helper service does not have any externally accessible socket, but starts a single regular container that looks like any other container. Whatever needs to be initialized must be done in the pre_start_hook or the post_start_hook.

This function must be called in controller context, for example in the late_initializer of Netplex_main.startup, but it can also be started later.

For an example, look at examples/netplex/helper_container.ml in the distributed source tarball.

For multi-threaded programs, Netplex_cenv.run_in_controller_context is the required companion function to start helper threads at any time. Multi-processing programs do not have such an easy way to add helpers. They should it at program startup time.

Known bug. The the helper component will be in "starting" state as long as the post_start_hook runs.
